With his work "The Wild Bees of Baden-Württemberg," Paul Westrich brought wild bees to the attention of both experts and the public. Now, he presents his comprehensive book on the wild bees of Germany. He provides detailed descriptions of the habitats of these creatures, their brood care and nests, their beneficiaries and adversaries, as well as the dependencies between bees and flowers, and outlines the threats to wild bees and their conservation. The book includes 565 profiles that contain all the essential information about the distribution, biology, and flight times of all native species. Over 420 of these are illustrated with live photographs and field identification features. Many species and behaviors are depicted for the first time in images.
